Question

Segment PQ bisects segment ST at point R.

SR=2x+2 and ST=40

Find the length of segment SR.

a
SR=9
b
SR=40
c
SR=36
d
SR=20

Answer 1

2(2x+2)=40, 4x+4=40, 4x=36, x=9..plug in 9..
2x+2, 2×9+2, 18+2, 20=sr


or simply 40÷2=20

Answer 2

Answer:

2(2x+2)=40, 4x+4=40, 4x=36, x=9..plug in 9..

2x+2, 2×9+2, 18+2, 20=sr
